From your question what I understand is that you want your one WICED device to act as a server and another WICED device to act as a client and then you want to display the server sent packets in the client terminal through USB/UART. If my understanding of your question is incorrect, please feel free to put forward your elaborated query. The exact example application is currently not available in WICED. But you can have a fair amount of idea by following the snip.tcp_client or snip.tcp_server applications where the server and client respectively are emulated by a Python Script. Based on these examples, I believe you can easily create your own application based on your requirement.

In that case, you can bring up the soft-AP using ethernet interface. In the snip folder of WICED SDK, you can find ping_ethernet application which requires some modification to implement this feature. Please let me know if you face any difficulty in implementing the same.

You can modify the ping_ethernet application and add an API call like wiced_network_up(WICED_AP_INTERFACE, WICED_USE_INTERNAL_DHCP_SERVER, &ap_ip_settings) to bring up the softAP interface and in the application makefile you can add

GLOBAL_DEFINES := WICED_USE_ETHERNET_INTERFACE which should help you out.
